French Protests Enter Fourth Week

The French Interior Minister says police have managed to bring under control anti-government protests which drew more than 100,000 people across the country. We hear from a protester about their demands, and how the demonstrations have been organised via Facebook. Also on the programme: President Trump says his chief of staff, John Kelly, will leave his job at the end of the month; and the sounds of Planet Mars.
